The remaining syntax from your post is almost identical in C and JS.

Press F12 in your browser (Chrome or Firefox) and have some fun with JavaScript ​in the "Console" tab, it's a good starting point :-) For example, copy paste the below code into the browser console and press ENTER.

function add (a, b) {
  return a + b;
}
console.log("1 + 1 =", add(1, 1));
add(1, 2);
